+- compatible : one of:
+        - "ns8250"
+        - "ns16450"
+        - "ns16550a"
+        - "ns16550"
+        - "ns16750"
+        - "ns16850"
+        - "nvidia,tegra20-uart"
+        - "ibm,qpace-nwp-serial"
+        - "serial" if the port type is unknown.
+- reg : offset and length of the register set for the device.
+- interrupts : should contain uart interrupt.
+- clock-frequency : the input clock frequency for the UART.
+
+Optional properties:
+- current-speed : the current active speed of the UART.
+- reg-offset : offset to apply to the mapbase from the start of the registers.
+- reg-shift : quantity to shift the register offsets by.
+- reg-io-width : the size (in bytes) of the IO accesses that should be
+  performed on the device.  There are some systems that require 32-bit
+  accesses to the UART (e.g. TI davinci).
+- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
+  RTAS and should not be registered.
+
+Example:
+
+        uart@80230000 {
+                compatible = "ns8250";
+                reg = <0x80230000 0x100>;
+                clock-frequency = <3686400>;
+                interrupts = <10>;
+                reg-shift = <2>;
+        };

+* Samsung's Watchdog Timer Controller
+
+The Samsung's Watchdog controller is used for resuming system operation
+after a preset amount of time during which the WDT reset event has not
+occured.
+
+Required properties:
+- compatible : should be "samsung,s3c2410-wdt"
+- reg : base physical address of the controller and length of memory mapped
+        region.
+- interrupts : interrupt number to the cpu.
